DYEING APPARATUS.

Specification of Letters Patent.

Patented Feb. 27, 1906.

A pli ation fil d November 11, 1905. Serial No. 286,826;

horizontal shallow pans, and particularly where an apparatus for dyeing is used such as described in -my application for United States patent, Serial N 0. 251,991, filedMarch 25, 1905.

When dyeing extra-wide pieces of cloth with the apparatus described in my abovereferred-to application, it is difficult to secure an even dye in the mid-portion of the upper surface of the goods. This is caused by the elimination of the dyestuif from the dye-bath during the extra-long travel from beneath the goods around its edge and to the mid-.

portion of its upper surface. To overcome this defect, I have modified the construction of this type'of apparatus, as shown in the accompanying drawings and described herein.

Primarily and essentially my invention consists of providingtwo inlet-pipesone on each side of the line of travel of the cloth during the dyeing operation. By this means the dye liquid is immediately projected on both sides of the cloth and may be immediately taken up by the fabric surfaces. I prefer that these pipes extend across the tray, particularly the pipe which is above the cloth, and at the outlet end of each trayI pre fer also to provide two outlets-one on each side of the line of travel of the cloth. One of these outletsthe one above the cloth-I prefer to form in the shape of the trough, so that the overflow may take place into the trough for substantially the'entire width of the machine, while the other outlet I prefer to form at the lower part of the machine in connection with an inverted-U-shaped baffle-plate which will direct the liquid from the bottom of the tray to such second outlet.

A second feature of my invention is to provide a means whereby the concentrated dyestufl may be continuously fed to the circulating system in much the same manner shown in my prior application, but means being provided for maintainin the concentrated dye liquid at a substantially constant head, so

. that a uniform mixture will be produced during the entire operation of the machine. I prefer to obtain this result by inserting in the piping connecting the reservoir which holds the concentrated dyestuff and the circulating system an auxiliary chamber provided with a float-valve of the ordinary type to keep a uniform head in said auxiliary chamber.

As will be obvious from the claims, my invention is not limited to that embodiment illustrated in the drawings or specifically described hereinafter; but the constructions and arrangements may be varied without departing from my invention as set forth in said claims.

In the drawings, Figure 1 is a sectional diagrammatic view of my preferred form of dye ing apparatus. Fi 2 is an enlarged sectional view of one o the trays of the same.

In this case, as in my prior application, the trays '3 are superposed one above another above a receiving-tank 1 and at a lower level than a feed-tank 2. connected by pipes 13 and 14, which are tank 2 I lead, preferably, a single feed-pipe 15 and tap off from it at suitable intervals with pipes ,16, each adjacent pipe 16 preferably leading to opposite ends of adjacent trays. The pipe 16 to each tray leads to two inlet openings or pipes 20 21, the pipe 20 extending across the tray and having openings throughout its length to permit the passage of the liquid into-the tray. This pipe is located upon one side of the line of travel of the cloth, while pipe 21 is-located upon the opposite side of the lineof travel of the cloth and adjacent to a baffle-plate 22, a ainst which the liquid may be projected from similar openings in the pipe and across the tray. Each tray 3 is preferably provided with a dam or baflie plate 4 near one end. In this invention the baflie-plate is in the form of an inverted U with an opening near its upper end, thus causing the liquid which overflows through said opening to be taken directly from the bottom of the pan. Near this plate 4 an outlet-pipe 18 is located, which connects with the pipe or pipes 17', adapted to lead their contents to the receiving-tank 1. At one side of the baffle-plate I provide a trough 40, extending substantially across the tray and connected by a pipe 41. with a pipe 17. This second trough-opening is adapted to take the liquid from the extreme top of the mixture to the tank 1..

The tanks 1. and 2arcthemselves joined by a pump 9. From the IIO Guide-rollers 5 are located within the trays to support and hold the fabric ofi the bottom or tray floor, while squeezing-rollers 6 (which I prefer to also use to draw the cloth through the trays) are located at one end of each tray to express the surplus dye solution from the cloth'as it emerges from the tray. A roller 19 may be located at the end of the tray opposite the squeezing-roller, if desired. Tension-rollers 7 are provided at the end of each tray to take up slack of the fabric in the wellknown manner.

At a convenient point within the circulating system of pipes and tanks I prefer to locate my improved means for inserting dyestuff into the dye-bath. I prefer to select the pipe 13 at this point and to lead the dyestuff by a pipe 12 from an auxiliary chamber 8, having a float-valve 11, controlling an opening from a container 10. The container holds a highly-concentrated dyestuif in-the liquid form. By inserting it at the point indicated the feed-pump 9 acts also as a mixing means for thoroughly mixing it in the dye-bath. By providing the float-valve a substantially uniform head of liquid. is

maintained in the auxiliary chamber, and hence a uniform supply of dyestuff introduced into the circulating system. In operation the cloth is passed through the trays in the same manner as described in my prior application. The liquid, however, is admitted on both sides of the cloth and substantially across the entire width of the tray. The liquid flows away from the trough after having the dyestuff eliminated from it to a considerable extent from two opposite sides of the cloth, one outlet being at the extreme up er surface of the solution and the other outet taking the solution from the extreme bottom of the tray.

What I claim is- 1. Apparatus for dyeing comprising a series of open relatively shallow superposed dyeing-trays and means for passing a piece of cloth successively'throughthe trays of the series and means for supplying dyeing liquid to the trays, comprising at least two inlet-pipes one on each side of thelinepf travel of cloth during operation.
